				 'filter' => Html::activeDropDownList($searchModel, 'id', ArrayHelper::map(Laptop::find()->asArray()->all(), 'id', 'laptop'),['class'=>'form-control','prompt' => 'Select Category']),
			],

?>

Solution

try add the realted use clause in your view

eg if you have all the models in common\models

use common\models\LapTop;

or

use your_app_name\models\LapTop;

assign the proper value to your_app_name

or for basic template try

use app\models\LapTop;

and for filter try using only

'filter'=>ArrayHelper::map(LapTop::find()->asArray()->all(), 'id', 'laptop'),
